Specification of Letters Patent.

Patented Feb. 18, 1919.

Application filed October as, 1918. Serial No. 259,985.

To all whom it may concern Be it known that I, ALois Killian, a J ugo- Slav, claimed as a subject of the King of Hungary, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Ice-Creepers, of which the following is a specification.

The primary object of the invention is the provision of means readily attached to the sole of any form of shoe for presenting a non-slipping surface to the roadway, whereby a person will be prevented from slipping while walking over snow and ice.

A further ,Object of the invention is the provision of a calk mei ber detachably secured to a shoe sole without injuring the shoe or the sole thereof, the device being instantly detachable at will and possessing great strength as well as being easy and inexpensive to manufacture;

With these general objects in view, the in vention will be fully described in connection with the accompanying drawing forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views.

In the drawing,

Figure 1 is a bottom plan view of aeportion of a shoe illustrating my invention operatively attached thereto.

Fig. 2 is a side elevation thereof.

Fig. 3 is a transverse sectional view of the same.

Fig. e is a top plan view of the invention detached from the shoe.

Fig. 5 is an end elevation thereof, and

Fig. 6 is a perspective view of the invention.

My invention broadly consists of a U- shaped calk member having each end 10 thereof in the form of a calk with a connecting portion 11 in the form of a plate adapted for positioning in flat engagement transversely of the instep portion 12 of a shoe sole 13 adjacent the heel 1 1 of the shoe.

The calks 10 have outer serrated edges 1n the form of sharpened teeth 15 which will project downwardly at the opposite sides of the sole 13 adjacent the forward corners of the heel 14 when the device is in use.

Integral lugs 16 are formed at one end of the plate 11 by being struck up from one of the calks 10 by cutting away such calk as at 17. The lugs 16 have sharpened flanges 18 inwardly extending from their outer free ends, the said flanges projecting over the plane of theupper face of the plate 11 when the device is positioned upon a shoe, the flanges 18 being then adapted to overlie one side of the sole 13.

A sllde plate 19 is flatly positioned beneath the plate 11 through a slot 20 in the calk 10 at the opposite end of the plate 11 over the lug 10. An upwardly-bent end or extension 21 of the plate 19 has a reduced portion 22 formed by opposite slots 23, whereby the end 21 may slide inwardly of an opening 24 in the end of the plate 11. The slots 23 receive the opposite sides of the opening 14 therein permitting and guiding the end 21 in its sliding movement toward and away from the lugs 16.

An inwardly projecting flange 25 is proected from the end 21 adapted to overlie the sole 13 of the shoe opposite the point of contact of the lugs 16. An operating screw 26 is journaled through a perforation 2? in one of the calks 10 and is swiveled as at 28 in the opposite calk while a depending portion 29 at the inner end of the plate 19 1S threaded upon the screw 26 between the calks. An operating handle 30 upon the free end of the screw 26 is employed for revolving the screw and forcing the plate 19 outwardly and inwardly, whereby the end 21 thereof and the flange 25 is forced toward and away from the lug 16 at will.

When the device is positioned as illustrated in Fig. 6 of the drawing with the plate end 21 retracted, the plate 11 is positioned flatly engaging the instep portion 12 of the shoe and upon turning the screw 26 by means of its end 30, the flange 25 is drawn inwardly over the ad acent side of the shoe sole 13. The creeper is securely clamped in this manner beneath the sole for'engaging the calks with the surface over which the person is traveling, it being seen that the teeth 15 project beneath the lower tread surface of the heel 14. By turning the screw 26 in the reversed direction, the flange 25 is released from the sole 13 so that the creeper may be readily removed therefrom.

What I claim as new is 1. A creeper comprising a U-shaped member having parallel end calks and a connecting plate, the said plate having an openingat one end, sole engaging lugs struck up from one of said calks adapted for overlying one end of the plate, a slider at the opposite end of the plate having an angular proa r: A, i;

lying one end of the plate, a slider the}, i

opposite end or" the plate having an angular projecting end movable inwardly and outwardly of said opening toward and away from said lugs, a screw journaled through one of said lugs and swiveled to the other lug, a depending portion upon said slider threaded upon said screw and a handle upon the free end of the screw.

3. An ice creeper adapted for attachment to the instep portion of a shoe comprising a plate positioned transversely beneath the see when in use with an opening at one end of the plate, parallel calks projecting from the opposite ends of the plate with slots'in one of said calks adjacent the opening of the plate, a slider positioned within the said slots having a projecting end provided with opposite notches whereby said end of the slider is adapted for movement outwardly and inwardly of said opening with the sides of said opening received within said notches, an inwardly projecting flange carried by said slider end adapted for overlying one side of the shoe sole when the plate is positioned for use, projecting flopies of this patent may be obtained for five cents each, by addressing the Commissioner said opening having terminal slte the flange of" said slider end adapted tor overlying lugs at the opposite end oi the plate from flanges oppothe opposite side of the shoe ole and operating means for said slider. d. An ice creeper adapted for attachment 1 plate positioned transversely beneath the ole when in use with an opening at one ad of the plate, parallel calks projecting il rom the opposite ends of the platewith slots in one of said calks adjacent theopen- {111g of the plate, a slider positionedwithin the said slots having a projecting end proi'ided with opposite notches wherebysaid end of the slider is adapted for movement outwardly and inwardly of said opening with the sides of said opening received within said notches, an inwardly projecting flange carried by said slider end adapted for over ying one side of the shoe sole when the plate is positioned for use, projecting lugs at the opposite end of the plate from said opening having terminalflanges opposite the flange ofsaid slider end adapted for overlying the opposite side of the shoe sole, a screw swiveled at one end in the 02th:

provided I with the slots and j ournaled through the opposite calk, a. projecting portion upon the end'of the plate between said-calks threaded upon said screw and an operating handle upon the outer free end of the screw.

In testimony whereof I aflixmy signature.
